I would like to suggest natural disasters such as trees getting struck by lightning when is raining and setting them on fire, or crops being affected by wild animals/birds.Maybe some tamable wolves into dogs, that we could use to defend our crops. (Not against players, but to keep wild animals away from the claim/crops)

There could be more things but I believe it would take more to implement them, such as terrain sliding for platforms unless building is finished before day/night cycle decay tick takes place, maybe minerals/ores that are stacked/poured on the ground could have some decay/wash away after too much rain,

Would also be cool if we would be able to create artificial lakes and swamps (if swamps would have any real usage) in which we could fish or that could create sand in time, those could also be affected by weather, getting flooded and quality/amount of fish decreasing because of it, maybe even some ducks that require the be placed near such lakes in some kind of special coops.

I know there are lots of suggestions and requests, that there is lots to work to do, and limited budged, otherwise would have created a long list of suggestions.
